Windows 10 lets you Pin folders, apps and shortcuts to executable files to the Start screen using the “Pin to Start” context menu. Using a registry tweak discussed in this post, you can pin any file (of any type) to the Start screen in Windows 10.
Start Regedit.exe and navigate to the following key:
Create a subkey named {470C0EBD-5D73-4d58-9CED-E91E22E23282}
Selecting the key {470C0EBD-5D73-4d58-9CED-E91E22E23282}, double-click the (default) value in the right-pane, and type “Pin to Start”. This step is optional, though.
Now, to pin a file, first create a shortcut to that file, right-click on the shortcut and click Pin to Start.
BONUS TIME!
To automate the above registry edit, copy the following lines to Notepad and save the file with .REG extension.
